The equation is $\"\"$ .

Make a table of values with five points for $\"\"$ and $\"\"$ and Graph the points from the tables.

Construct the tables.

Graph:

Plot the points $\"\"$ and $\"\"$ .

Solve the equation.

$\"\"$ (Original equation)

$\"\"$ (Subtract $\"\"$ from each side)

$\"\"$ (Apply additive inverse property : $\"\"$ )

$\"\"$ (Add $\"\"$ to each side)

$\"\"$ (Apply additive inverse property : $\"\"$ )

$\"\"$ (Divide each side by $\"\"$ )

$\"\"$ (Cancel common terms)

Therefore,the value of $\"\"$ is $\"\"$ .

$\"\"$

Find the intersection point.

Graph the line equations $\"\"$ and $\"\"$ .

$\"\"$

Observe the graph:

The lines intersect when $\"\"$ .

This is the $\"\"$ -coordinate for the point of intersection on the graph.

Graph:

$\"\"$

b. The value of $\"\"$ is $\"\"$ .

The lines intersect when $\"\"$ .

This is the $\"\"$ -coordinate for the point of intersection on the graph.
